Configuring RSVP Reliable Messaging

When acknowledgment is not received, the trigger message is re-transmitted using the retransmission parameters configured on the interface.

Note

Note

RSVP refresh messages never require acknowledgment, even when reliable messaging is enabled.

To enable RSVP reliable messaging on an interface, complete the following steps.

  1. Configure the device.
    device# configure
  2. Enable the MPLS router.
    device(config)# router mpls
  3. Enable MPLS-capable interfaces for configuration and specify the individual ethernet interfaces.
    device(config-router-mpls)# mpls-interface ethernet 0/13
    In this example, the specified ethernet interface is 0/13.
  4. Enable LDP parameters
    device(config-router-mpls-eth-0/13)# rsvp
  5. Enable RSVP reliable messaging on the selected interface.
    device(config-router-mpls-eth-0/13-rsvp)# reliable-messaging

Example

The following example shows the enabling of RSVP reliable messaging on an ethernet interface 0/13.

device# configure 
device(config)# router mpls
device(config-router-mpls)# mpls-interface ethernet 0/13
device(config-router-mpls-eth-0/13)# rsvp
device(config-router-mpls-eth-0/13-rsvp)# reliable-messaging

The previous commands enable RSVP reliable messaging on interface 0/13 with all parameters set to their defaults (or to settings previously configured on this interface, if any).
